Cosina Voigtländer Expands Its APO-Lanthar 28mm f/2 to Multiple Mounts
Japanese company Cosina Voigtländer has expanded its APO-Lanthar 28mm f/2 Aspherical lens lineup to include Sony E-mount and Nikon Z-mount mirrorless cameras, following the earlier Leica M-mount release.
The lens preserves the optical formula of the M-mount version, consisting of 12 elements arranged in eight groups, including six anomalous partial-dispersion glass elements and two double-sided aspherical elements. A floating focus mechanism ensures consistent sharpness across the image plane, while the optical design minimizes axial chromatic aberration. The lens can focus as close as 0.28 meters, providing a maximum magnification of 1:6.9, which is significantly closer than the rangefinder-coupled M-mount variant.
Both the Sony E and Nikon Z versions are strictly manual focus: Cosina uses a full-metal helicoid mechanism designed to deliver smooth, precise adjustments, allowing for subtle fine-tuning. The Sony E-mount lens weighs 325 grams, and the Nikon Z-mount 350 grams, compared with 265 grams for the M-mount version. Both versions retain 49mm filter compatibility, though there are differences in exterior styling. The Sony version has diamond-knurled focus and aperture rings with red markings, giving a modern tactile feel, while the Nikon Z model uses a more vintage-inspired texture with yellow markings, similar to the original VM-mount lens. The included lens hoods differ slightly between mounts, adapting to the physical dimensions and aesthetics of each system.
The lens features a 12-blade aperture, producing nearly circular openings for smooth bokeh and controlled point-light rendering, and offers a 74° angle of view suitable for wide-angle photography without exaggerated distortion. Electronic contacts on the Sony version allow for EXIF data recording, in-body stabilization, and focus aids such as magnification and focus peaking.

Cosina has scheduled the Sony E-mount version for release in December 2025, followed by the Nikon Z-mount lens in January 2026. Early pricing information from Japan suggests a cost of approximately $850, with U.S. pricing expected to be higher due to import tariffs.
